After several operations, I can confirm that the illumination performance in general is very good. One has the possibility of a point or environment illumination (both modes can be dimmed). Even with tempo runs the weight of the headlamp affected not stable seat or the route illumination. For jogging, the illumination is always sufficient.
Both the lamp housing and the headband are meticulously crafted. The material quality is also okay. The lamp housing is at least resistant to water splashes. The lens surface is naturally susceptible to scratching and requires the use of a certain amount of care.
Operation of the lighting functions is very simple; it has graduated settings: high beam, environment illumination, dimming, strobe mode, night vision mode (red light for map reading) and a lock mode (transport safety).
The duration of the power supplied batteries is also very good. The remaining capacity of the batteries is indicated by indicator on the lamp housing.
Overall, I am very satisfied with performance, material quality and processing of the headlamp and can fully recommend for the purpose mentioned above.
